public interface ExpressionVisitor
```
This interface is used to traverse the JPQL parsed tree. It follows the Visitor pattern. It visits the concrete instances of Expression.
Provisional API: This interface is part of an interim API that is still under development and expected to change significantly before reaching stability. It is available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.
